> Hi,
> I am using camel-elasticsearch5 component of Camel 2.20.1.
> I have found and issue. The description follows.
> *If you use Map or String in message body for SEARCH operation, "size" and "from" parameters are always ignored hence you always get just default 10 results.*
> For example - if your map contains query like this: 
> (in terms of simplicity - following is String representation of the map):
> {code}
> {size=50, query={query_string={query=status:ACTIVE}}, from=0}
> {code}
> Issue I suspect is present in class: _org.apache.camel.component.elasticsearch5.converter.ElasticsearchActionRequestConverter_
> and its method 
> _public static SearchRequest toSearchRequest(Object queryObject, Exchange exchange)_
> {code}
> // line 191...
> if (queryObject instanceof Map<?, ?>) {
>             Map<String, Object> mapQuery = (Map<String, Object>)queryObject;
>             // Remove 'query' prefix from the query object for backward compatibility
>             if (mapQuery.containsKey(ElasticsearchConstants.ES_QUERY_DSL_PREFIX)) {
>                 mapQuery = (Map<String, Object>)mapQuery.get(ElasticsearchConstants.ES_QUERY_DSL_PREFIX);
>             }
>             try {
>                 XContentBuilder contentBuilder = XContentFactory.contentBuilder(XContentType.JSON);
>                 queryText = contentBuilder.map(mapQuery).string();
>             } catch (IOException e) {
>                 LOG.error(e.getMessage());
>             }
>         }
> // queryText then used on line 220...
> searchSourceBuilder.query(QueryBuilders.wrapperQuery(queryText));
> searchRequest.source(searchSourceBuilder);
> return searchRequest;
> {code}
> Inner if condition basically extracts only query part from the map 
> {code}
> query={query_string={query=status:ACTIVE}
> {code}
> and *"size" and "from" get lost from the query*
> {code}
> // line 194...
> if (mapQuery.containsKey(ElasticsearchConstants.ES_QUERY_DSL_PREFIX)) {
>                 mapQuery = (Map<String, Object>)mapQuery.get(ElasticsearchConstants.ES_QUERY_DSL_PREFIX);
> // ...where ElasticsearchConstants.ES_QUERY_DSL_PREFIX = "query"
> }
> {code}
> Same issue is with usage of the String in the message body:
> {code}
> // line 203
> } else if (queryObject instanceof String) {
>             queryText = (String)queryObject;
>             ObjectMapper mapper = new ObjectMapper();
>             try {
>                 JsonNode jsonTextObject = mapper.readValue(queryText, JsonNode.class);
>                 JsonNode parentJsonNode = jsonTextObject.get(ElasticsearchConstants.ES_QUERY_DSL_PREFIX);
>                 if (parentJsonNode != null) {
>                     queryText = parentJsonNode.toString();
>                 }
>             } catch (IOException e) {
>                 LOG.error(e.getMessage());
>             }
>         }
> {code}
> Only workaround for this is to use *SearchRequest* object in a message body where you can explicitly set "size" and "from" on SearchSourceBuilder object. For example:
> {code}
> SearchRequest searchRequest = new SearchRequest("my_index")
>             .types("my_type")
>             .source(new SearchSourceBuilder().query(QueryBuilders.wrapperQuery("my:query"))
>                 .size(50).from(0));
> {code}
> I don't know what was the developer's intention for having such a condition which removes these parameters from the query.
> Thank you very much in advance if anybody can have a look and verify if this is a valid concern.
